L Fixed Aperture
Choose whether aperture varies with zoom position.
M Noise Reduction
At slow shutter speeds, pictures may be affected by “noise” in the form of
randomly-spaced, brightly-colored dots concentrated in dark parts of the image.
Use this option to reduce noise at slow shutter speeds. Enabling noise reduction
increases the time needed to record pictures after they are shot.
When noise reduction is performed, the x icon is displayed in the monitor during
shooting (
A 6).
On
In A and M modes, aperture is kept as close as possible to selected f-number. To
prevent selected f-number from exceeding exposure range at new zoom position,
set aperture to around f/5.1–f/7.3.
Off (default setting)
Aperture varies with zoom position.
a Auto (default setting)
Noise reduction is performed at slow shutter speeds, likely to result in pictures
affected by noise.
When a setting other than [Single] or [Intvl timer shooting] is selected for
[Continuous], or when a setting other than [Off] is selected for [Auto bracketing],
noise reduction will not be performed.
M On
Noise reduction is applied to pictures shot at shutter speeds slower than 1/4 sec.
[On] is recommended when shooting at slow shutter speeds.
Only [Single] or [Intvl timer shooting] can be selected for [Continuous]. [Auto
bracketing] cannot be applied.
